DEVICE FOR REMOVING WALL-PAPER.

To all 'La-7mm it may concem:

Be it known that I, GUSTV AYnns, a citizen of the United States,residing at Tashington, District of Columbia, have invented certain newand useful Improvements in Devices for Removing Tall-Paper, of which thefollowing is a specification.

My invention relates to improvements in means for detaching paper orother coverings from walls, and it consists in the constructions,combinations and arrangements herein described and claimed.

An object of my invention is to provide an improved device constructedto cause positive impingement of a series of rapidlyfiowing steam jetsover the entire area of paper under treatment, thereby insuring athorough and uniform moistening of the adhesive backing with a minimumconsumption of steam.

A further obj ect of my invention is to provide a compact and durabledevice for removing wall paper from position in a cleanly and asepticmanner.

My improved construction operates very efiiciently in practice, andovercomes the defects of previous constructions in which a large portionof the steam is not positively directed against the paper undertreatment and is condensed without eficient action, with a resultantsteam waste and incomplete and irregular moistening of the adhesivebacking.

In the accompanying drawings, forming a part of this application and inwhich similar reference numerals indicate corresponding parts in theseveral views: Figure 1 is a side elevation, partly broken away,illustrating one embodiment of my invention; Fig. 2 is a front elevationof the construction shown in Fig. 1, with a portion of the nozzlepartition removed, a-ndDFig. 8 is an enlarged plan of the supply nozzleshown in Figs. 1 and 2.

Referring to the drawings, 1 indicates a lcasing provided with an openfront for engaging a section of the wall paper to be removed. The bottomwall of the casing comprises two plates 2 which incline upwardly both ina forward and lateral direction to provide a depressed medial portion,through Specification of Letters Patent.

which leads a fluid-supply pipe 8. A supply nozzle 4: is shown securedto the bottom plates 2 coaxially with the supply pipe 3, and providedwith apertures 5 extending to the upper surface of said plates. Thesteam supply through the pipe 3 and nozzle 4 can be convenientlyControlled by any suitable valve 6, actuated by a link 7 and a lever 8pivoted on the casing handle 9. A partition 10 is spaced within thecasing 1 to provide a recessed front, and carries a series of expandingnozzles 11 constructed to directthe steam at high velocity in a seriesof overlapping jets against the wall. paper; thereby insuring a thoroughand uniform penetration of the entire area of said paper. The partition10 terminates at 12 slightly above the middle portion of the inclinedbottom plates 2, to permitthe free passage of any condensed steam notabsorbed by the wall paper; such condensation being directed by theplates 2 to the nozzle apertures 5, where itencounters the incomingsteam and is directed by an injector action to the casing 1 and nozzles11.

I have illustrated preferred constructions, but changes could be madewithin the spirit and scope of my invention.

I claim:

1. In a device of the Character described, the combination of a casinghaving an open front to engage a wall, a partition therein spaced fromthe front and carrying a plurality of expanding nozzles for directing afluid at high velocity in a series of overlapping jets against the wall,and means for supplying fiuid under pressure to said cas- 1n0f.

2. In a device of the Character described, the combination of a casingformed with a bottom wall inclined upward both forwardly and laterallyfrom its medial portion, a partition spaced from the front of saidcasing and terminating above the middle portion of the bot-tom wallthereof, a series of ex` panding nozzles in said partition, and afluid-supply pipe communicating with the lowest portion of said inclinedbottom wall.

3. In a device of the Character described, the combination of a casingformed with a bottom wall inclined upward both forwardly in presence oftwo Wtnesses.

and laterally from its medial portion, a partition spaced from the frontof said casing and terminating above the middle portion of the bottomwall thereof, a series of expanding nozzles in said partition, afluid-supply pipe communicating With the lowest portion of said inclinedbottom Wall, and a supply nozzle supported on said inclined bottomVVitnesses A.
